Constantly adjust budget and scheduling?

It's called being a responsible adult with children! (I honestly think this guy is very immature.)

Don't let your kids grow up without each other. I think that it's cruel to rip siblings apart. They even try to keep siblings together in foster care situations when possible.

Any guy with half a brain would know that he can have the same darn budget every month. It's called saving! Save more one month, spend more the next. i.e. Eaven things out. He just wants to have more money to have fun.

I hate to say it, but get rid of the kittens. Give them away. If you can't afford a divorce, you can't afford kittens.
